This patch fixes existing specs to totally conform to tox py27 environment
tests as specified by tests/test_titles.py. Semantic information of all
existing specs has not been changed.
Specifically, this patch makes the following changes:
* Fixes all titles and subtitles' capitalization inconsistencies:
defaulting to only having the first word being capitalized (this seems
to be the general rule in group-based-policy-specs);
* Adds missing titles and subtitles to some specs;
* Changes tests/test_titles.py for consistency: only 1st word capitalized;
* Changes tests/tests_titles.py: subtitle count inside Testing or
Documentation impact no longer restricted to 0.
